Product Overview
The Kyocera 0.045 SGM09855 is a solid-carbide 4-flute, square-end micro end mill from Kyocera's precision micro-tooling program, engineered in Japan for high-accuracy CNC micro-milling. With a cutting diameter of 0.045″ (1.143 mm) on a rigid 1/8″ (3.175 mm) shank, it is built for slotting, fine profiling, shallow pocketing and detail work on machining centers, high-speed spindles and CNC engraving platforms.
A Titanium Aluminum Nitride (TiAlN) coating adds a hard, heat-resistant surface layer (approx. 3,300 HV) that protects the cutting edge in abrasive and high-temperature cuts, extending tool life up to 3× versus uncoated carbide.

Chipbreaker Profile
Instead of a pressed chipbreaker, this micro end mill manages chips through its flute and gash design:
- Deep, polished flute gullets give chips maximum evacuation volume at 0.045″ diameter, preventing re-cutting and clogging.
- 30° helix lifts chips smoothly out of the cut while keeping cutting forces low and chatter-free.
- Center-cutting gash geometry allows plunging and ramping entries without a pilot hole.
- Fine edge preparation (≤5 µm) shears material cleanly, producing small, manageable chips even in gummy alloys.
Recommended Applications & Workpiece Materials
| Workpiece Material (ISO Class) | Suitability | Notes |
|---|---|---|
| ISO P — Carbon & alloy steels (≤45 HRC) | Excellent | Full slotting & side milling |
| ISO M — Stainless steels (303/304/316) | Very Good | Light-to-moderate radial engagement |
| ISO K — Cast irons | Very Good | Profiling & facing |
| ISO N — Aluminum & copper alloys | Good | Use air blast / MQL to avoid built-up edge |
| ISO S — Titanium & Inconel | Good | Low SFM, high feed, rigid setup |
| ISO H — Hardened steels (45–55 HRC) | Good | Finishing passes only |
Application Map by Operation
| Milling Operation | Suitability | Guideline |
|---|---|---|
| Full Slotting | ★★★★☆ | Axial DOC ≤ 0.5×D (0.022"), reduce feed 20% |
| Side Milling / Profiling | ★★★★★ | Radial WOC 5–10% of D for best finish |
| Shallow Pocketing | ★★★★☆ | Ramping entry at 3–5° |
| Micro Engraving / V-Carving | ★★★★☆ | Use minimum qty lubrication |
| Plunging / Drilling | ★★★☆☆ | Center-cutting; peck in 0.1×D steps |
| 3D Contouring | ★★★★☆ | Small stepovers (≤10% D) for fine surfaces |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed | Spindle Speed | Feed per Tooth | Feed Rate (4FL) |
|---|---|---|---|---|
| Aluminum / Brass / Copper | 260 SFM | 22,100 RPM | 0.0003"/tooth | 23.9 IPM |
| Mild / Low-Carbon Steel | 120 SFM | 10,200 RPM | 0.0003"/tooth | 11.0 IPM |
| Alloy Steel (≤35 HRC) | 100 SFM | 8,500 RPM | 0.0003"/tooth | 9.2 IPM |
| Stainless Steel (304/316) | 80 SFM | 6,800 RPM | 0.0003"/tooth | 7.3 IPM |
| Titanium Alloys | 60 SFM | 5,100 RPM | 0.0003"/tooth | 5.5 IPM |
| Hardened Steel (45–55 HRC) | 45 SFM | 3,800 RPM | 0.0003"/tooth | 4.1 IPM |
Values are starting recommendations for rigid setups; adjust ±20% for machine stiffness, holder runout and coolant.
Operating Guidelines
- Keep tool-holder runout below 0.0002" (5 µm) TIR — runout is the #1 cause of micro-tool breakage.
- Use the shortest possible gauge length; never extend the tool beyond the flute length plus clearance.
- Climb mill whenever machine rigidity allows for better surface finish and tool life.
- Start at 70% of recommended feed and speed, then optimize upward in 10% steps.
- Use air blast, mist or flood coolant appropriate to the material; avoid thermal shock on interrupted cuts.
- Retire the tool at the first sign of edge chipping or size drift — micro tools fail catastrophically when worn.
Toolholder Compatibility
| Holder System | Specification | Notes |
|---|---|---|
| ER Collet Chuck | ER8 / ER11, 1/8" collet | Best all-round choice for micro milling |
| Shrink-Fit Holder | 1/8" (3.175 mm) bore | Maximum rigidity & ≤3 µm runout |
| Precision Milling Chuck | 1/8" capacity | Good for general machining centers |
| Hydraulic Chuck | 1/8" bore | Excellent vibration damping for fine finishes |
| Spindle Interface | HSK-E25/E32, BT30, CAT40 or straight-shank adapters | Match to machine spindle |
